Are you sending these files over HTTP? Doesn't HTTP provide the ability to compress files between server and client?

What are you ziping between the server and the client? Some Zip files of DLL files made with pkzip (or the shell) are with the WCF service, the Silverlight 5 app lazily loads them and adds the assemblies. There are some quite large charting DLLs that make the SL app loading horribly slow if they're in the XAP. The background loading works nicely and isn't much code. It was at the receiving end of one of the zip files as a blob that I found DotNetZip couldn't handle them. Greg
